A tugboat with a displacement of 50 tonnes and resistance of 750 kN is towing a 75-tonne bargewith resistance of 1000 kN. The tugboat has a propeller generates thrust of T to move it forward,while the barge is non-propelled. Determine the thrust and the force exerted by the rope on thetugboat, given that it takes 35 seconds for the tugboat to uniformly increase its speed to 13.5knots.
5. A box with a mass of 100 kg was originally attached to the spring at position A. After that, pressure was applied to the box until The spring compresses to a distance of X - 1 m and releases it, causing the box to move upwards along the inclined floor. If the incline has and = the coefficient of friction uk = 0.3, find the box that can travel along the incline for a maximum distance in meters.

A couple of figure skaters are executing a move called the "death spiral" as shown in the image below. The male skater on the left is swinging his partner around him on the ice and we can assume that he is rotating without translating. The coefficient of friction between the female's skates and the ice is 0.02. The male skater is applying a constant moment of 8 lb-ft about the axis of rotation to keep the spin going. If the couple is initially spinning at 5 rad/s, calculate their final angular velocity after 6 seconds. Simplify this problem and treat the female as a 140 lb particle that is spinning 6' from the axis of rotation only in the horizontal plane. For full credit, draw an FBD and clearly define your system using polar coordinates. 8 lb-ft Axis of Rotation 6 ft 11:38 AM Type here to search 58°F Partly sunny 3/30/г022
